Cautions about using the Sensors

• Cautions about using the temperature-humidity sensor TR-3100
• The sensor can measure temperature within the range of 0 to 50°C and humidity within the range of 10 to 95%RH.
• Only use the sensor within these ranges.
• If extremely severe temperature changes occur, the humidity measurements may appear abnormal.
• Once the sensor’s temperature becomes stable, the measurements will return to normal.
• This sensor is not waterproof. Do not get wet.
• When measuring with the temperature-humidity sensor in an environment of 0 to 50°Cand less than 30%RH, the measurements may sometimes fluctuate. This is not abnormal

Handling the temperature-humidity sensor

•  The service life of humidity sensors can vary greatly depending on operating environment.Periodic calibration may be required.
• During use the temperature-humidity sensor will accumulate impurities (dirt) on the surface of the sensor is being used in a bad environment (smoky or dusty places) it may be necessary to change the sensor sooner.
•  When the temperature-humidity sensor is not being used, please place it in the attached vinyl bag with the drying agent included and store it in a cool dark place with a temperature of between 5 to 25°C and a humidity of below 30%RH.
•  Attached to the temperature-humidity sensor are two stickers: a wetness detection sticker and a temperature detection sticker. If eitherof the stickers shows abnormality, you should change the old sensor to a new one immediately.
• Wetness Detection Sticker
• Informs you that the sensor has been wet.
• Temperature Detection Sticker
• Informs you that the sensor measured a temperature measurement over 60°C.

About Thermo Recorder TR-73U

Outline
TR-73U Thermo Recorder is a data logger capable of measuring, displaying and recording temperature, humidity, and barometric pressure data. TR-73U has a total of three channels: one temperature, one humidity, and one barometric pressure channel. The data recorded into the TR-73U units can then be downloaded quickly via USB cable to your computer whereby with our software you can easily process the data into graphs, tables, save to files and/or print it out. Moreover, it is possible to connect more than one unit at the same time.

Basic Functions

• Barometric Pressure Measuring Range : 750 to 1100 hPa The TR-73U with the internal barometric pressure sensor can measure and record in a range of 750 to 1100 hPa.

• Temperature Measuring Range: 0 to 50°C (with supplied temp-humidity sensor)

• The TR-73U with the internal temperature sensor can measure and record in a range of -10 to 60°C, but by purchasing one of our optional temperature sensors it is possible to measure and record in the wider range of -40 to 110°C.

• Please take a look at our full range of optional sensors to find one to match your application. (T&D Website: HOME > PRODUCTS > TR-73U > Options)

• Humidity Measuring Range : 10 to 95%RH The TR-73U with the sensor included in this package can simultaneously measure and record temperature in a range of 0 to 50°C and humidity in a range of 10 to 95% RH.

• Amount of Recorded Data : 8000 readings x 3 channels One channel can record and hold up to 8000 measurement readings. At the longest recording interval of 60 minutes, recording can continue consecutively for 1 year.

• 10 Months of Operation with just 1 AA Alkaline Battery Our low energy consumption design gives you ten months of continuous operation with only one AA alkaline battery. This gives you the freedom to use the data loggers in places where they can be left alone for long periods of time, such as, in transportation or warehouse.
  NOTE:

• – Battery life varies depending upon the type of battery, the measuring environment, the frequency of communication, and the ambient temperature in which it is used.
  Specifications and explanations used in this User’s Manual are based on operations carried out with a new battery and are in no way a guarantee of your actual battery life.
  Also, if the recording interval is less than 10 seconds, battery life will be much shorter.

•  Battery Life Warning Display
  When the battery power becomes low, a battery life warning signal will appear in the unit’s LCD display.
  If the battery power becomes even lower the unit will automatically go into sleep mode in order to protect the data.

• 15 Recording Intervals
  Select from 15 recording intervals (from 1 second to 1 hour) to meet your needs. Select from 2 Recording Modes
  One-time Mode : When the number of recorded readings reaches 8000, [FULL] will appear in the unit’s LCD display and recording will automatically stop.
  Endless Mode : When the number of recorded readings reaches 8000, the oldest data readings will be overwritten and recording will continue.

• Current Readings Monitoring Display
  With our software T&D Recorder for Windows, you cannot only monitor the current measurements at a set interval, but can view those measurements in a continually changing graph.
  You can simultaneously display the current measurements and corresponding graphs for the number of units you have connected.

• Adjustment Function
  By entering the adjustment values beforehand with the software, it is possible to view and record the adjusted measurement values.
  There are two methods of adjustment: adjusting by one point or adjusting by two points. Adjustment for differences will be based upon the following simple equation Y=aX+b.
  X equals the measured value and Y equals the value after adjustment.

Before Using

• Important Notes about the Installation Procedure of  T &D Recorder for Windows.
• In order to use a USB connection to communicate between the TR-73U and a PC, it is necessary to install the software T&D Recorder for Windows and the USB driver.
• Before connecting the TR-73U to the computer with a USB cable, make sure to first install the software.
• When you connect the TR-73U to the computer before installing the software, the following message may appear. In that case, click [Cancel] and disconnect the USB cable.

   NOTE:
   If a unit is left without a battery for more than 2 minutes, all data will be lost, so please work quickly when changing the batter

Turning ON the Power

1.  By holding in the POWER switch at the left side, the unit will turn on.

Turning OFF the Power

• By holding in the POWER switch, the unit will turn off.
• During recording, the power cannot be turned off. Please stop recording first and then turn off the power.
• Even if the power has been turned off, the recorded data will be saved.
• However, if the battery power is totally lost, all data will be lost, so please download data as soon as possible to avoid losing any necessary data.

Connecting the Sensors

• To avoid poor connections, be sure to push the sensor connector securely into the jack.

•  When using the temperature-humidity sensor in environments where the temperature is 0 to 15 °C and humidity under 30 RH, there may occur changes in measurement readings. This is not a malfunction.
  NOTE:

•  If a sensor extension cable is being used with the data logger connected by USB to your computer, electromagnetic waves may cause large errors in measurements.

•  For details about handling the temperature-humidity sensor, please refer to page 6 “Cautions about using the Sensors” of “Safety Precautions and Instructions”
